I am collaborating with a group that is building a multiphoton microscope. Can anyone recommend resolution test samples for 2P and second/third harmonic imaging? Pictures are nice, but we would like to test performance as well.

Dear Doug,

our application specialist from Olympus told me to use fluorescent beads for quality management.  The 1-2µm beads for finding the right planar  and 500nm  beads for measuring (the shape). Perhaps you can use even smaller beads up to resolution frontiers.

All the best
Katrin

dear doug,

urea crystals are a good sample if you just want to know whether you can generate any SHG at all, but they don’t have much structural detail and aren’t very biologically relevant. collagen is an excellent second harmonic generator, and one of the biological materials you are likely to image in the end. you should be able to fix a bit of tissue and keep that around, although fresh material might have better ultrastructure. there are many excellent sources:

there is a dense layer of collagen in the mouse intestine between the smooth muscle and base of the intestinal crypt. the structural detail is very rich, and you should be able to resolve very thin fibrils within larger bundles. this one is my personal favourite; if you contact me off-list i can send you images.

alternatively, you might image rat tail tendons:

Hi Doug,

The bead method is the standard way.  Just be aware that theres a
rather annoying tradeoff between light emission and accuracy of the
PSF measurement, with tiny beads giving you a nicer PSF but also being
a lot harder to find/see (particularly if your PSF or scanners are not
optimal).

You can also buy beads that are pre-distributed on glass slide, but
the ones I've ordered tended to be quite sparse.  These are probably
meant for a 10+ fps commercial microscope with low latency preview,
but can be really painful on a home built system, particularly if
you're still working on the software and don't have a well optimized
preview/scanning routine debugged yet.  In that case I'd recommend
putting a lot of beads on a coverslip, or even sonicating them into
PDMS so that you have less trouble finding them.

Mike

Re: resolution standard for MP and SHG?

In reply to this post by Kurt Anderson-3
Dear Doug,

I would also like to point out that Argolight slide are compatible with MP and exhibit SHG contrast on their patterns. The only thing is that you must be extremely careful to use the minimal amount of energy possible with MP on the slide, as you the 100 GW/CM^2 limit is for instantaneous irradiance no averaged one.

Best regards,
Gautier

Doug,

for THG resolution we used nanoparticles, eg. TiO2. We have tried
sunscreen, but it didn't work, too much THG signals from the fat
droplets. So pure particles are needed, attached to a slide or in
agarose or the like. Zinc oxide nanoparticles have been described to
generate SHG*. I would expect them to also produce THG, so you might get
two birds with one stone.

For z-resolution in THG, a glass/water interface should do: With a
dipping water objective, immersion water directly on a glass slide
(previously marked with a black dot to find the focal plane in bright
field or fluorescence). This sample is my favorite to check illumination
intensity across the field of view.

If you should go for the collagen fibers mentioned by Kurt, in addition
to the SHG from the fiber core, you'll get a THG signal from the
fiber/surroundings interface. At high resolution and with a sufficiently
thick fiber the THG signal is hollow at the core, were the SHG signal
is. I am not sure though how well they will do for determining
resolution, my impression was that some may be pretty thick.

Steffen

The PS Speck microspheres work quite well, they are bright enough for 2 photon excited fluorescence. With 170 nm they are a bit big to be point sources, but I found them to be a good compromise.

Doug, one of the best standard for SHG and checking your polarization
state of your fundamental is starch. Grab a potato from your pantry,
take a small piece and liberate starch grains between two cover glass in
a drop of water, you are good to go. You can keep that tuber in your
refrigerator for at least a month or two.
